Which of the following biomolecules typically contains both nitrogen and phosphate?

Which of these substances stores the most energy?

A biomolecule that is a large, complex set of chains composed of alternating subunits called nucleotides has which of these functions in the cell?

Many plants have waxy coatings on some surfaces. This coating reduces water loss because it is not water-permeable. This waxy coating is which of the following types of organic molecule?

Which of the following macromolecules are a prominent part of animal connective tissue such as cartilage and keratin?

What process results in two complete strands of DNA from one original strand?

During prophase, chromosomes become visible, the spindle forms, the nucleolus and nuclear envelope disappear. In which cellular process does prophase occur?

Leukemia is cancer of the body’s blood-forming tissues. A leukemia patient’s bone marrow produces abnormal white blood cells which do not function properly. A pharmacology company is trying to develop drugs to regulate the production of abnormal white blood cells.  Which of the following processes is most likely affected by this new drug?

During DNA replication, a chemical called DNA polymerase acts as an enzyme to quickly bond nucleotides on the complementary strand. DNA polymerase belongs to a large class of biomolecules that perform most of the actions carried out by organisms called ―

Chromosomes are composed of two types of biomolecules. One of the biomolecules in chromosomes is called DNA, which functions as the genetic code. The other biomolecules in chromosomes are called histones, which bind the DNA tightly for cell division. Genes in DNA have the code for making histones.  Based on the information above, which types of biomolecules are in chromosomes?

Telophase is a stage of a cellular process that begins after the chromosomes have moved to opposite poles of the cell. During which cellular process does telophase occur?

As cancerous cells multiply uncontrollably, abnormal tissue masses form. These masses of tissue are called –

Mutations in genes which regulate the cell cycle could lead to –
